Good morning dear.

The US was involved in the Vietnam war because it felt that the victory of Ho chi minh goverment would start a domino effect-the communist governments would be established in other countries of indo- china.

The effects were :-

... about 47,244 US personal lost their lives and about 303,704 wounded..

..Many were critical of,the government for being,involved in a war which could not be won.

..When the youth were drafted for the war the anger spread.

..Many of those sent were of the minorities and children of working class..

The media was also influential in supporting as well as criticising the war..

From these we can say...

These lead to various strikes and protest accross the country

Thus:-

AMERICA FOUGHT 2 WARS..

ONE WITH VIETNAM AND ONE WITH ITSELF..

Hope this will help you and plz mark me as brainliest.

From your encouragement i would definitely help you in futures
